I’ve got say, I’ve been using one of my new ones to read by every night before bed and it’s a really pleasant light for that purpose. Nice soft light, a relatively wide beam, lightweight and easy to hold for long periods of time. I bought them thinking I might give them to my children… I might have to buy more if I’m going to do that!

And here’s the second mod that was needed, 10 minutes with a common solder iron, this is the easiest host ever.

The led is the bit higher current-capable RWN05-32K-C-EX from rngwn (see link), I measured 3007K, 97.2CRI, R9 97 and duv -0.0034 for this particular led ( Love , how nice can a tint get?)

The 220 resistor was replaced by a solder blob, the battery current went up to 135mA and the output was better than I thought: 25 lumen on a alkaline and 21 lumen on a old crappy NiMh. A major brightness update over the 7 lumen stock.

Did this mod, and its a great improvement. I got the LED too hot when soldering it in, and it flickers then goes out after a few minutes, but a great mod, thanks Djozz!

Once I get another of these LEDs in that I didn’t kill with heat, I’ll pot it with RTV and use it as my keychain light

I love my C01 and C01s lights. My question is – do any of you have an easy way to get that (*&(^& O=ring into that little hole? It took me about an hour to get them fastened to the four C01 lights I bought as give-aways. I couldn’t resist the $3.99 price. And as far as I am concerned, the $3 extra for faster shipping was worth the expense.

Just got mine. There’s one annoyance that the battery bore is a little too small and some oversized AAA batteries won’t fit in there.

I tried cramming a Tesco alkaline in there and it refused to go in. I ended up leaving a nasty scrape on the battery casing after the ordeal.

 

Searching for High CRI leds since 2010...

 

Has finally gotten to the bottom after 10 years of delving deep into that rabbit hole of them high CRI lights...

 

High CRI, high quality lights doesn't need to be expensive, or is it?

Buy another one. The bore holes vary quite a bit.

You mean the keyrings? I’m using pliers for the really small ones.

Ah I was actually going to try that. Was also going see how it would look with film on the reflector. Have to wait for the lights to arrive first.

I guess I really did get the short end of the stick here.

Out of four I received from Djozz today, only one that can take the Tesco alkaline.

I also had some trouble taking the Tronic Ni-MH cells (from Lidl) from some of the last C01 and even the C01S I recently bought. I will give them away with alkalines inside, but it is a bummer to have these differences between samples Tired

Yes, AA/A Lidl cell are larger,but the Ikea (white) fits well and are great cells.
1 year and are still full charge and their capacity is real with good discharge
A pack of 4 cost almost one C01,what a steal!

I mod mine with 221 resistor and it’s been running 16 days straight.

Here are photos next to tritium to get the idea of brightness. It’s enough light to walk to toilet in pitch black.

no sign of alkaline leakage too Smile

It arrived today with two diffusers so now I have two nice little Sofirn’s:

Next I need to get C01S with green body. Also I want to get atleast orange and green trits, because C01R already has a red one. The aaa-light and trit bug has bitten me.

Why does a light with low power like this work fine indoors but not adequate outdoors to see where you walk?

Because indoors it’s the only light, and outdoors there are other lights that may disturb your view.
Chance that you are in “night vision” mode is higher than when you just stepped out of your car.

Or: distances indoors are smaller than outdoors (my front yard is bigger than my bedroom) Wink

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

As an emergency light it is fine outdoors, it will light your way, but a light with more output and a hotspot works nicer.

distance differences call for lumen differences

indoor distances are shorter than some outdoor distances

something at arms reach, a plate of food while seated at a table,
does not need a lot of lumens..

no matter indoor or outdoor.. the key is the distance you want to illuminate

the door handle to the toilet indoors… the zipper pull on a tent door outdoors… the keyhole on the car door.. all these things are within hands reach.. so the same lumens suffice.. no matter indoor or out.. its all about the distance

The C01 is a 7 lumen light. As a rule of thumb thats good for distances of 7 feet or less.

I’ve just received this light thinking that it had more than one mode, my bad for not reading before..

I prefer the C01s.

both is better

I prefer the C01 as a close range light, and the C01S as a longer range light.

The C01 beam can show all the food on the plate at the same time, the C01S can only show part of the meal, due to the narrower beam

the C01S can spot a cat 20 feet up a tree,
otoh
the C01 works better to see the cat on my lap Smile

Sorry if this is a stupid question. Do the sofirn c01 Sophia comes without any glass? The led is exposed to open air?

Yes and no. It’s not a “bare” LED with silicone coating or dome. It’s a 5 mm LED with hard plastic housing, sitting in an aluminum “reflector”.

correct, that is normal, no glass lens needed nor available.

the 5mm LED is manufactured with a waterproof optical dome, and installed with an O ring around the base. No water or dirt can get into the electronics.

if you had ever seen a Fenix E01 (which cost more and was not High CRI), it had the same no glass lens. It is a very durable design.

Enjoy! Smile

Thanks Jon and Sammy! I was surprised that there is no glass lense but I don’t think sofirn will forgot the lense there must be something I’m missing. Lol

This is the first kind of light I have with this design. Very interesting.

Just adding to the dataset. Received order from Sofirn website, blue and orange not potted, all other colours potted (didn’t order brown so can’t comment).

There’s some variation in the tint though and unfortunately for me the potted ones look the worst.

Also, the new colours are very nice, the green is lovely, as are the blue and red (now deeper / richer).

What is the best solder league to put on the positive driver contact to protect it from scratch?
In the past I used Sn-Pb 60/40 but after a little use it blackened and had to be cleaned, I thought it was caused by the presence of lead

Buy enough C01 lights, Sari. I’ve used one from the initial batch multiple times a day. Still intact pads.

Smile, you cannot kill them all.

You can also get gold contacts.

pure 24K is probably too soft.

plated Contacts should work better
